Laserliner: Precision in Every Dimension
Laserliner is a division of UMAREX GmbH & Co. KG in Arnsberg and develops, manufactures and distributes electronic measurement technology for use on construction sites, in trade, industry and the DIY sector. The product range includes line lasers, cross-line lasers and rotation lasers, laser and rolling distance meters, digital spirit levels and inclinometers, material and air moisture meters, thermal imaging cameras, digital endoscopes for video inspection in industry and automotive, multimeters, detection devices and temperature measuring devices. Its roots lie in the development of Europe's first affordable laser spirit levels in 1993; since 2002, Laserliner has been a separate measurement technology division of the Umarex Group. Most of the products have been revised and are made of recycled plastic to reduce the use of virgin plastics. At the Arnsberg site, in the new building at Gut Nierhof since autumn 2023, devices are calibrated and repaired in the company's own service center for all of Europe; every calibration is followed by an issued factory inspection certificate. As an OEM supplier, the company distributes to over 40 countries.
